I'm currently wondering if its the right time to upgrade my gpu. I have the 7970ghz edition and I thought I would wait for 390x to come out but with these prices, its hard to pass up. I could get a 290x with alien isolation and star citizen for 300 on amazon right now or a gtx 780ti for 370 on newegg with borderlands; the pre sequel. Does anyone have any advice if the upgrade is worth it, and which one you'd choose if it was?
